The dynamically changing topological nature of Mobile Adhoc Networks (Manet) makes the routing a challenging one. There are many on demand routing protocols has been discussed earlier for the improvement of Quality of Service (QoS) in Manet. We propose an Optimal Link Managed On Demand routing protocol (OLMOD) for the development of quality of service of routing in mobile adhoc networks. The proposed method learns available paths and maintains them in route matrix throughout the transmission and the path link will not be discarded if there is no transmission at the path suddenly. The path link will be maintained for a particular time according to transmission delay and a constant period of time even though there is no data transmission through the link. Unlike standard aodv algorithm the path will not be deleted from route table if there is no data transfer periodically. The proposed system reduces the latency generated by reinitiating the route discovery.
